Highly transparent silicone fluid compound |
| 摘要 |
A highly transparent silicone paste composition is formulated by mixing: (a) 100 parts by weight of a long chain alkyl-modified silicone fluid having a viscosity of 50-5,000 cS at 25 DEG C. represented by the formula <IMAGE> wherein R1 is a monovalent saturated straight chain hydrocarbon group having 4-18 carbon atoms and accounts for 10-50 mol % of all the Si substituents; m and n are integers such that 0</=m</=500, 5</=n</=500, and 5</=m+n</=500, and a and b are either 0 or 1; (b) 1-30 weight parts of a fumed silica whose specific surface area is no less than 130 m2/g; and (c) 0.1-20 weight parts of an alkoxysilane represented by the formula XcSi(CH3)dR2e, wherein R2 is an alkoxy group; X is selected from <IMAGE> <IMAGE> c is 0 or 1; d is 0, 1 or 2; e is 2 or 3; and c+d+e=4, or a hexamethyldisilazane represented by the formula [(CH3)3Si]2NH.
